This application claims the benefit of priority to U.S. ProvisionalApplication No. 62/540,693, filed in the U.S. Patent and TrademarkOffice on Aug. 3, 2017, the entire contents of which are incorporated byreference as if fully set forth herein.

TECHNICAL FIELD

The present disclosure relates generally to container lids, and moreparticularly, to a leak-proof container lid with foam insulation.

BACKGROUND

Container lids generally include mechanisms for sealing an aperture of acontainer through which fluid may enter and/or exit (e.g., a screw-oncap, a flip cap, a push cap, etc.). To access fluid within the containerwhile the container lid engages the container, a user may typically moveor remove a closure portion of the lid relative to the aperture of thecontainer such that a fluid path into the container may be provided,allowing the user to drink through the lid. When the user wishes to sealthe container (e.g., for transport), the user may adjust the closureportion of the lid such that the fluid path is sealed. Ideally, theclosure portion seals the fluid path in a leak-proof manner so thatleakage of fluid within the container is prevented.

Another important consideration with respect to container lids involvestemperature control. Users often prefer to preserve the temperature offluid within a container, particularly when the container has beenfilled with a hot or cold beverage. Problematically, modern containerlid designs are effective either at preserving fluid temperature orpreventing leaks, rather than effective at both.

SUMMARY

The present disclosure provides a drink-through container lid that isboth leak-proof by way of a pivoting closure mechanism that reversiblyseals an opening in the container lid and insulated by way of foaminsulation that fills a hollow body of the lid housing. The result is acontainer lid that prevents leakage of fluid within a container whilealso preserving the temperature of said fluid.

According to embodiments of the present disclosure, a container lidincludes: a lid housing having a hollow body, an opening formedtherethrough, and a thread pattern formed thereon for mating thecontainer lid to a container; a closure mechanism coupled to the lidhousing and operable to reversibly seal the opening; and foam insulationdisposed within the hollow body.

The foam insulation can be formed so as to at least partially surroundthe opening, and can also be formed to substantially fill the hollowbody. The opening may be disposed between the thread pattern and thefoam insulation.

The thread pattern may be formed on the lid housing so as to faceoutwardly with respect to the container lid. Thus, the outwardly facingthread pattern may be operable to couple with an inwardly facing threadpattern of the container.

A proximal end of the closure mechanism can be connected to the lidhousing at a connection point, and the closure mechanism can be operableto pivot about the connection point. The closure mechanism may beoperable to pivot between an open position in which the opening is openand a closed position in which the opening is sealed.

The closure mechanism may include a hook portion disposed at a distalend of the closure mechanism that is configured to receive a rim of thelid housing, thereby reversibly holding the closure mechanism in placewhen the closure mechanism is in the closed position. The rim that isreceived by the hook portion may be disposed at a same side of the lidhousing as the opening, and the hook portion may include a grip portionprotruding outwardly from a distal end of the hook portion with respectto the container lid.

In addition, a recess portion can be formed near a distal end of theclosure mechanism that is configured to mate with a protrusion portionof the lid housing, thereby reversibly holding the closure mechanism inplace when the closure mechanism is in the open position. The protrusionportion may be formed on an end of the lid housing that is diametricallyopposed to the opening.

The closure mechanism may further include an opening plug disposed neara distal end thereof that is configured to fit within the opening so asto reversibly seal the opening when the closure mechanism is in theclosed position. Also, the closure mechanism may further include a ventplug that is configured to fit within a vent formed through the lidhousing and through the foam insulation so as to reversibly seal thevent when the closure mechanism is in the closed position.

A range of movement of the closure mechanism between the open positionand the closed position may be approximately 180 degrees.

Additionally, one or more air pockets can be disposed within the hollowbody adjacent to the foam insulation. In this regard, one or more wallsmay extend outwardly from an inner surface of the hollow body and comeinto contact with the foam insulation, thereby forming the one or moreair pockets.

Also, a thickness of a first region of the foam insulation can be lessthan a thickness of a second region of the foam insulation. The firstregion can be an end of the foam insulation proximate to the opening,and the second region can be an opposite end of the foam insulation.

DETAILED DESCRIPTION OF THE EMBODIMENTS

Hereinafter, embodiments of the present disclosure will be described indetail with reference to the accompanying drawings. As those skilled inthe art would realize, the described embodiments may be modified invarious different ways, all without departing from the spirit or scopeof the present disclosure. Further, throughout the specification, likereference numerals refer to like elements.

The terminology used herein is for the purpose of describing particularembodiments only and is not intended to be limiting of the disclosure.As used herein, the singular forms “a,” “an,” and “the” are intended toinclude the plural forms as well, unless the context clearly indicatesotherwise. It will be further understood that the terms “comprises”and/or “comprising,” when used in this specification, specify thepresence of stated features, integers, steps, operations, elements,and/or components, but do not preclude the presence or addition of oneor more other features, integers, steps, operations, elements,components, and/or groups thereof. As used herein, the term “and/or”includes any and all combinations of one or more of the associatedlisted items.

Referring now to embodiments of the present disclosure, the disclosedcontainer lid features a drink-through design (i.e., a fluid path isformed through the lid allowing a user to drink fluid inside thecontainer without removing the lid) that is both leak-proof by way of apivoting closure mechanism that reversibly seals an opening in thecontainer lid and insulated by way of foam insulation that fills ahollow body of the lid housing. The result is a container lid thatprevents leakage of fluid within a container while also preserving thetemperature of said fluid. The disclosed container lid also features athread pattern which may be fashioned to face outwardly with respect tothe lid, so as to couple with an inwardly facing thread pattern of thecontainer, thereby creating a tight seal that increases leak preventionand insulative properties of the lid.

FIG. 1 is an exploded view of a container lid 100 according toembodiments of the present disclosure. As shown in FIG. 1, the containerlid 100 includes a lid housing 110 having a hollow body within whichfoam insulation 130 is disposed. Different varieties of foam may beutilized for insulation in the container lid 100, such as expandedpolystyrene (EPS) or the like, and the foam insulation 130 may beinserted into the body of the lid housing 110 using various techniquesknown in the art such as foam injection molding or the like. In oneexample, the lid housing 110 may include a separate top portion andbottom portion 112 during assembly of the container lid 100. The lidhousing 110 may be fashioned using any suitable material, such asacrylonitrile butadiene styrene (ABS) or other thermoplastic polymers,for example.

The foam insulation 130 may be inserted within one of the portions ofthe lid housing 110, and the top and bottom portions may then beadjoined (e.g., ultrasonically welded) to produce the foaminsulation-filled lid housing 110. The foam insulation 130 may bedisposed within the lid housing 110 using any suitable techniques knownin the art. The foam insulation 130 can fill an entirety of the hollowbody of the lid housing 110, thereby enhancing insulative properties ofthe lid 100.

The foam insulation 130 may be made of a constant thickness or, in somecases, the foam insulation 130 may be made of variable thickness, asshown in FIGS. 2 and 13. For instance, the thickness of a region of thefoam insulation 130 proximate to the opening 150 may be less than thethickness of a region of the foam insulation 130 at an opposite end asthe opening 150. In one example, the thickness of the region of the foaminsulation 130 proximate to the opening 150 may be formed within a rangeof 13 mm to 17 mm, whereas the thickness of a region of the foaminsulation 130 at an opposite end as the opening 150 may be formedwithin a range of 20 mm to 26 mm (though the dimensions of the foaminsulation 130 are not limited thereto). Further, the thickness of aregion of the foam insulation 130 proximate to the connection point Pmay be less than the thickness of the region of the foam insulation 130proximate to the opening 150. Thus, the foam insulation 130 may beformed having a plurality of different thicknesses depending on variousfactors, such as the shape of the lid housing 110.

An opening 150 is formed in the lid housing 110 to provide a fluid pathfrom the container 180 through the lid housing 110, allowing a user todrink through the lid housing 110. The opening 150, shown in greaterdetail in FIGS. 2 and 3, may be formed in any suitable shape, such asoval-like or semi-circular. The opening 150 is also formed through thefoam insulation 130, such that the foam insulation 130 is formed topartially surround the opening 150, as shown in FIGS. 1 and 2.Alternatively, the foam insulation 130 can be formed to completelysurround the opening 150. Because the foam insulation 130 can at leastpartially surround the opening 150, while filling the body of the lidhousing 110, insulative properties of the container lid 100 are enhancedwithout compromising a user's ability to drink through the lid 100.

In addition, a closure mechanism 120 is coupled to the lid housing 110and operable to reversibly seal the opening 150, thereby preventingleakage of fluid within the container 180 while the closure mechanism120 is in a position to seal the opening 150, regardless of thetemperature of the fluid inside the container 180. As shown in FIG. 2, aproximal end of the closure mechanism 120 may be connected to the lidhousing 110 at a connection point P, and may be connected in mannerallowing the closure mechanism 120 to pivot about the connection pointP. The closure mechanism 120 may be fashioned using any suitablematerial, such as polypropylene (PP) or other thermoplastic polymers,for example.

As shown in FIG. 6, the closure mechanism 120 may pivot between a closedposition, in which the opening 150 is sealed (by a plug 160 of theclosure mechanism 120), and open position, in which the opening 150 isopen, and the closure mechanism 120 is stowed away to permit the user todrink through the opening 150. A top surface of the lid housing 110 maybe formed in various ways to permit such movement of the closuremechanism 120, such as providing space proximate to the connection pointP to enable rotation of the closure mechanism 120, providing space onthe top surface to accommodate the closure mechanism 120 in the openand/or closed position to enable the closure mechanism 120 to fit flushwith the lid housing 110, and so forth. Different techniques may beemployed to connect the closure mechanism 120 to the lid housing 110,such as a pin, prongs, or the like.

As further shown in FIG. 1, a thread pattern 140 is formed on anexterior of the lid housing 110, such that the opening 150 may bedisposed between the thread pattern 140 and the foam insulation 130, formating the container lid 100 to a container 180. The thread pattern 140may be formed on the lid housing 110 so as to face outwardly withrespect to the container lid 100 such that the outwardly facing threadpattern 140 is operable to couple with an inwardly facing thread pattern142 of a container 180, as shown in FIG. 5. The outwardly facing threadpattern 140 can create a tighter seal with the container 180 than aninwardly facing thread pattern, helping to further increase leakprevention and insulative properties of the lid 100.

FIG. 8 is another exploded view of the container lid 100 according toembodiments of the present disclosure. As shown in FIG. 8, a gasket 170may be disposed to surround a portion of the lid housing 110 to preventfluid leakage between the container lid 100 and the container 180 towhich the lid 100 is coupled. The gasket 170 may be fashioned using anysuitable material, such as silicone, for example.

FIG. 2 is a cross-sectional view of the container lid 100 according toembodiments of the present disclosure. As shown in FIG. 2, an opening150 traverses the lid housing 110 to allow a user to drink fluid insidethe container 180 through the lid 100. The foam insulation 130 fills thehollow body of the lid housing 110 and may be formed to at leastpartially surround the opening 150. The closure mechanism 120 seals theopening 150 when in the closed position demonstrated in FIG. 2.

In one example, a proximal end of the closure mechanism 120 may becoupled to the lid housing 110 at a connection point P, and a distal endof the closure mechanism 120 may include a hook portion 122. The hookportion 122 may be configured to receive a rim 114 of the lid housing110, thereby reversibly holding the closure mechanism 120 in place whenthe closure mechanism 120 is in the closed position demonstrated in FIG.2. The opening 150 may be disposed at the same side of the lid housing110 as the rim 114 that is received by the hook portion 122.Furthermore, the hook portion 122 may include a grip portion 124protruding outwardly from a distal end of the hook portion 122 withrespect to the container lid 100 to allow a user to easily grip the hookportion 122 and rotate the closure mechanism 120 between the closed andopen positions.

Additionally, the closure mechanism 120 may include a recess portion 126formed near the distal end of the closure mechanism 120. In one example,the recess portion 126 may be formed into the hook portion 122, as shownin FIG. 2. The recess portion 126 may be configured to mate with aprotrusion portion 116 that is formed on an end of the lid housing 110that is diametrically opposed to the opening 150. When the closuremechanism 120 is in the open position and the recess portion 126 mateswith the protrusion portion 116, the closure mechanism 120 can bereversibly held in place. This enables the closure mechanism 120 to bestowed away when a user wishes to drink through the opening 150.

FIG. 3 is a top perspective view of the container lid 100 in an openposition according to embodiments of the present disclosure. As shown inFIG. 3, the closure mechanism 120 can pivot to an open position in whichthe opening 150 is open (i.e., unsealed). Here, the closure mechanism120 can be stowed away and held in place (until a user manually movesthe closure mechanism 120) due to the recess portion 126 of the closuremechanism 120 mating with the protrusion portion 116 of the lid housing110, as described above.

An opening plug 160 may be disposed near a distal end of the closuremechanism 120. The opening plug 160 can be formed with a shape and depthto fit within the opening 150 so as to seal the opening 150 when theclosure mechanism 120 is in the closed position (see, e.g., FIGS. 1 and2). The opening plug 160 can be made of any material suitable forensuring a leak-proof seal of the opening 150, such as a resilientmaterial like a thermoplastic elastomer (TPE) or thermoplastic rubber.

In addition, a vent 152 may be formed through the lid housing 110 andthe foam insulation 130. The vent 152 may ensure a smooth flow of fluidthrough the opening 150, as is generally known in the art. To preventleakage through the vent 152, the closure mechanism 120 may furtherinclude a vent plug 162 that is formed with a shape and depth to fitwithin the vent 152 so as to seal the vent 152 when the closuremechanism 120 is in the closed position. Like the opening plug 160, thevent plug 162 can be made of any material suitable for ensuring aleak-proof seal of the vent 152, such as a resilient material like a TPEor thermoplastic rubber. The opening plug 160 and vent plug 162 may beindependently fashioned and affixed to the closure mechanism 120, orfashioned as a single unit (see, e.g., FIG. 8) and contemporaneouslyaffixed to the closure mechanism 120.

FIG. 4 is a bottom perspective view of the container lid 100 accordingto embodiments of the present disclosure. As shown in FIG. 4, theopening 150 and vent 152 may be formed to traverse the lid housing 110and foam insulation 130, thereby providing fluid paths from the apertureof the container 180 to outside of the container 180 while the containerlid 100 is coupled to the container 180.

FIG. 5 is a perspective view of the container lid 100 with an outwardfacing thread pattern 140 operable to engage with an inward facingthread pattern 142 of a container 180 according to embodiments of thepresent disclosure. As shown in FIG. 5, the outwardly facing threadpattern 140 formed on an exterior of the lid housing 110 can engage withan inwardly facing thread pattern 142 of the container 180. Theoutwardly facing thread pattern 140 can be formed on the lid housing 110within an outer circumference of the lid housing 110. That is, the outercircumference of the lid housing 110 (i.e., the circumference of anupper portion of the lid housing 110) may be greater than thecircumference of the portion of the lid housing 110 on which the threadpattern 140 is formed, such that the thread pattern 140 fits inside ofthe container 180, and the container wall fits flush with the upperportion of the lid housing 110. The outwardly facing thread pattern 140can create a tighter seal with the container 180 than an inwardly facingthread pattern that fits outside of the container wall, helping tofurther increase leak prevention and insulative properties of the lid100. The container 180 may be any suitable size and type of container,such as, for example, a stainless steel container with avacuum-insulated body.

FIG. 6 is a perspective view of a range of motion for the closuremechanism 120 between an open position and a closed position accordingto embodiments of the present disclosure; and FIG. 7 is a perspectiveview of the opening 150 of the container lid 100 and a partially openedclosure mechanism 120 according to embodiments of the presentdisclosure. As shown in FIG. 6, the closure mechanism 120 can freelyrotate between a closed position, in which the opening 150 is sealed,and an open position, in which the opening 150 is open and the closuremechanism 120 is stowed away. In the closed position, the closuremechanism 120 may be reversibly held in place by the hook portion 122receiving the rim 114 of the lid housing 110. Similarly, in the openposition, the closure mechanism 120 may be reversibly held in place byrecess portion 126 mating with the protrusion portion 116 of the lidhousing 110. The closure mechanism 120 may pivot away from eitherposition by a user exerting a force on the closure mechanism 120 (e.g.,the grip portion 124) to rotate the closure mechanism 120.

A range of motion of the closure mechanism 120 between the open positionand the closed position may be approximately 180 degrees. That is, theclosure mechanism 120 when in the open position is offset byapproximately 180 degrees from the closure mechanism 120 when in theclosed position, as shown in FIG. 6. The closure mechanism 120 mayrotate freely within the range of motion, as demonstrated by thepartially opened closure mechanism 120 shown in FIG. 7. It should beunderstood that the range of motion of the closure mechanism 120 may bealtered in any suitable manner, and thus the disclosed container lid 100is not limited to any one particular range of motion.

Additional views of the container lid 100 are provided in FIGS. 9-13.FIG. 9 is a top view of the container lid 100 according to embodimentsof the present disclosure; FIG. 10 is a bottom view of the container lid100 according to embodiments of the present disclosure; FIG. 11 is aleft side view of the container lid 100 according to embodiments of thepresent disclosure; FIG. 12 is a front view of the container lid 100according to embodiments of the present disclosure; and FIG. 13 is across-sectional view of the container lid 100 along line A-A in FIG. 12according to embodiments of the present disclosure.

The container lid 100 may include an alternative insulation arrangement,as shown in FIGS. 14-17. In this regard, FIG. 14 is another explodedview of a container lid according to embodiments of the presentdisclosure; FIG. 15 is another cross-sectional view of a container lidaccording to embodiments of the present disclosure; FIG. 16 is anotherexploded view of a container lid according to embodiments of the presentdisclosure; and FIG. 17 is another cross-sectional view of a containerlid along line A-A in FIG. 12 according to embodiments of the presentdisclosure.

Instead of filling an entirety of the hollow body of the lid housing 110with the foam insulation 130, a combination of foam insulation 130 andone or more air pockets can fill the hollow body of the lid housing 110.For instance, the bottom portion 112 of the lid housing 110 can bereplaced with bottom portion 190 which may include an arrangement ofwalls 192 forming multiple air pockets 194, such that the air pockets194 are disposed within the lid housing 110 in conjunction with the foaminsulation 130. When paired with the foam insulation 130, the resultingair pockets 194 act as an additional barrier helping to prevent thetransfer of heat energy from a liquid within the container 180 to thebody of the lid 100.

As shown in FIGS. 14-17, the walls 192 may extend outwardly from aninner surface of the hollow body of the lid housing 110 and come intocontact with the foam insulation 130. For example, the walls 192 mayextend upwardly from the bottom of the inside of the lid housing 110such that the foam insulation 130 is disposed above the air pockets 194,or alternatively, the walls 192 may extend downwardly from the topportion of the inside of the lid housing 110 such that the foaminsulation 130 is disposed below the air pockets 194. The walls 192 maybe arranged in, for example, a grid pattern, a honeycomb pattern, and soon. The height and thickness of the walls 192 may also vary according todesign preference. The bottom portion 190 and/or walls 192 may befashioned using the same material as the lid housing 110, e.g., ABS orother thermoplastic polymers.

Although specific materials are mentioned above, any and all portions ofthe container lid 100 described herein may be made of any suitablematerial such as, but not limited to, plastic, metal, ceramic, orcombinations thereof. Plastics of the present disclosure may include,for example, polyethylene terephthalate (PET), high densitypolyethylene, low density polyethylene, vinyl, polypropylene, andpolystyrene. Additionally, suitable metals of the present disclosure mayinclude aluminum and iron (e.g., steel, stainless steel, and cast iron).Any seal herein disclosed may be made of any suitable sealing materialsuch as, but not limited to rubber, plastic, soft plastic and/or foam.

Accordingly, the container lid disclosed herein features a drink-throughdesign that combines leak-proofness and insulation. A pivoting closuremechanism reversibly seals an opening in the container lid to eliminateleaks through the opening. Foam insulation fills a hollow body of thelid housing to insulate the contents of a container. The result is acontainer lid that prevents leakage of fluid within a container whilealso preserving the temperature of said fluid. The disclosed containerlid also features a thread pattern which may be fashioned to faceoutwardly with respect to the lid, so as to couple with an inwardlyfacing thread pattern of the container, thereby creating a tight sealthat increases leak prevention and insulative properties of the lid.

While there have been shown and described illustrative embodiments thatprovide for a leak-proof container lid with foam insulation, it is to beunderstood that various other adaptations and modifications may be madewithin the spirit and scope of the embodiments herein. For example, theembodiments have been primarily shown and described herein with relationto a pivoting closure mechanism that rotates between an open and closedposition. However, the embodiments in their broader sense are not aslimited, as the closure mechanism may be replaced with another mechanismcapable of sealing the lid opening, such as a push-button mechanism or aslide mechanism. Thus, the embodiments may be modified in any suitablemanner in accordance with the scope of the present claims.

The foregoing description has been directed to embodiments of thepresent disclosure. It will be apparent, however, that other variationsand modifications may be made to the described embodiments, with theattainment of some or all of their advantages. Accordingly, thisdescription is to be taken only by way of example and not to otherwiselimit the scope of the embodiments herein. Therefore, it is the objectof the appended claims to cover all such variations and modifications ascome within the true spirit and scope of the embodiments herein.
